The Wellington Phoenix striker has capped off a career-best season by winning the Johnny Warren Medal, the honour for the competition's best player.

He was the third Phoenix player to take out the prestigious award after Shane Smeltz in 2008-09 and Nathan Burns in 2014-15.

Krishna also took out the league's Golden Boot with 18 goals this season, breaking Jeremy Brockie's club record for most goals in a season in the process.

The 31-year-old Fijian international is off-contract and attracting interest from around the league for a big-money marquee deal.

He was already said to have rejected an offer from expansion club Western United, while Sydney FC and Western Sydney Wanderers are also chasing his signature. The Phoenix were understood to have offered him a lucrative new deal.

The Johnny Warren Medal is awarded by a judging panel of former professional players, referees, technical experts and members of the media for the A-League regular season. Panel members from each of the four groups were appointed to vote on a 3-2-1 basis on every match.

Krishna received 31 points from the panel, two ahead of Adelaide United's Isaias and Perth Glory's Neil Kilkenny.
